We show that these features do not indicate the absence of spin correlations between planes perpendicular to the rods. Rather, they arise because neutron scattering is largely insensitive to the three-dimensional correlations which are present throughout. We present two very simple models which exhibit a pristine incarnation of such scattering rods. This provides a physical picture for their appearance, elucidates the role played by monopole excitations, and identifies conditions conducive to their observation.
